,Application filed :ruly 3,

To all whom t may concern:

Be it known thatI, JOHN KALTENBAGH, a citizen of the United States of America, and a resident of Waterloo, Blackhawk County, Iowa, have invented certain new and'useful Improvements in Sash Fasteners, of which the vfollowing is a specification.

My invention relates to improvements in sash fasteners, and the object of my improvement is to supply means for releasably fastening either or both of a pair of window sashes in adjusted positions asdesired.

This object I have accomplished by the means which are hereinafter described and claimed, and which are illustrated in the accompanying drawings, in which Fig. 1 is an elevation of one face of a pair of window sashes and of the casing therefor, parts being sectioned or broken away, said sashes and casing being equipped with the coacting elements of my said fastening means. Fi 2 is a vertical cross section taken throug said casing and sashes looking toward the inner face of the main plate, and Fig. 3 is another vertical cross section of said casing and sashes, but looking toward the outwardly directed face of said main plate. Fig. 4 is an enlarged perspective view of said main plate with the lfastener elements mounted thereon. Figs. 5 and G-are like horizontal cross sections of parts of the casing, showing parts of said sashes, and showing the fastener elements which are respectively mounted on both coactingly, and as unengaged in Fig. 5, and as engaged in Fig. 6.

The numeral 8 denotes a window casing of the usual type, containing a pair of glazed window sashes 10 and 11 mounted to move past each other vertically in parallel planes. One vertical j amb has a vertically elongated recess 9, covered by a main plate 1, having on its outwardly directed face a number of longitudinally alined horizontal brackets 3 oriiced in line to receive a vertical shaft or rod 4 on which a number of cross-bars 5 are loosely mounted to rock horizontally therey 1922. Serial No. 572,686.

are as shown in Fig. 5 equally extended into said slots 2.l

The numeral 12 denotes a plate which is secured to the edge of the sash 11.which abuts jupon the main plate 1 over the row of pins 6 which carry said springs .7, andthis plate 12 has a like plurality `of horizontally elongated holes 18, of theI same size and shape as the holes 2 in the plate 1 and positioned for occasional registration therewith.

Upon the top edge of the other sash 10 a hollow boxing 14 is fastened longitudinally with one end close to the main plate 1. This boxing contains a slide-bolt 15, and a portion of the top ofthe boxing is removed and recessed at 17 at one side, and the bolt 15 has a finger-stud 16 extending angularly therefrom in the open part of the boxing, for manual use in sliding the bolt to and fro toward and into either of the holes 2 in the plate 1 with which it may be placed in alinement when the sash 10 is moved up or down in said casing.

When thelower sash 10 is either in its lowermost position as shown in the figures, or in certain elevated positions, the bolt 15 may be thrust into an alined hole 2, engaging and pushing farther into the recess 9 the alined pin 6, thus rocking the cross-bar 5 only on which this pin is mounted, so that the spring 7 about the opposite pin is compressed while said opposite pin 6 moves into the registering holes 2 and 13 in said overlapping plates 1 and 12. The bolt may then be rocked over to engage its stud 16 with one of the notches 17 in the boxing 14 to secure the fastening elements above mentioned in positions to lock both sashes either closed, or in any adjusted positions.

When the bolt is rocked back, and released, the compressed spring 7 reacts to slide the bolt back, whereby both sashes are unfastened. It is apparent that either or both sashes may thus be held locked in any positions of relative adjustment as desired.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is:

1. vThe combination of a slide-bolt ada ted to be mounted on the lower sash o a 105 window, a plate mounted over a recess in the window-j amb and having longitudinallyalined opposite holes adjacent both its lon tudinal edges respectively in the paths of e lower and upper sashes, a plate mounted on the upper sash of the window having a longitudinal row ofsockets in itsiaoe, over one osaidi rows ofl holes, ahd=`refsilientl controlled rook-bodies mounted in the jambreoess and having pins extending into the opposite holes in the plate, said slidebolt edges respectively in the paths of the lower and. y.upper sashes, said holes A being transversely elongated, a .plate mounted; fon the upper sash of the window having a longitudinal row of sockets in its face over one of said rows of holes, l and resiliently-controlled roek-bodies mounted in the jamb-re- 'Cess' and havingpins extending toward the oppositeholes `said plate, said slide-bolt when moved toward said plate entering an alinedhole therein to push outwardly-` onev pin. on-a rook-body -to roo-lil the latter to lpush the oppositeipin thereon init@ an ldined socketin the plateonfsaid uppersash.
